Nothing ruins a good Christmas like three cloged bathrooms. On the day before Christmas all of ourshower drains and toilets were cloged. We tried almost everything ourself except for calling theplumber and this is what we have done so far to try to solve the problem. First, we use drano / liquid plumber chemicals but it didn't help much. Second, we tried using a 25 feet snake on the shower drains but it didn't help much either. Third, we tried a 50 feet snake from the outside of the house (there are 2 pipe openings on the side of the house, one is right next to the kitchen and on is next to one of the bathroom).We suspect there is a blockage somewhere in the main waste line, but using the snake didn't helpat all so is there something we can do ourself? or it is time to call the plumer?
